Hello all. I am using DDE spy to watch messages between Lookout and an
older DDE application developed by the company I work for. I cannot achieve
a DDE Advise link with Lookout being the requestor and the other app the
server. Lookout does a DDE Poke right after it finds the other app via DDE.
The text it tries to Poke is "Dogs barking.".
Is anyone familiar with what is going on? I can get Lookout to talk to
other DDE apps easily. My older app is not expecting the poke so I am
assuming it rejects the connection. Below is the DDESPY messages for
reference. Thanks to anyone in advance for your help!
(Quite a few Initiates take place before this section...)
